Automatic sterilizing unit for out/return air in central air conditioner

Abstract

An automatic disinfector for the output and return air of central air conditioner features that the needle-type negative-high voltage ionizing electrodes, positive-voltage advective-adsorption plate electrodes with Ag-carried electric conducting adsorption layer on its both surfaces, and high-voltage plate electrodes for generating electric field are sequentially and alternatively fixed on insulated base, and the disintecting ultraviolet lamp is between two adjacent advective-adsorption plate electrodes. Its advantages are high speed and effect, and low resistance to air.

Description

technical field [0001] The invention relates to an automatic disinfection device, in particular to an automatic disinfection device for air outlet and return air of a central air conditioner, belonging to the field of air purification. Background technique [0002] The atypical pneumonia (SARS) virus that broke out in the world this year has brought great difficulties to the extensive prevention and control work due to its unknown transmission route, diversity, rapid mutation, unknown survival time, and no specific drug treatment, but it is relatively clear The best preventive measures can only stay in the aspects of more ventilation, more disinfection, and maintaining personal hygiene. In the process of virus transmission, the central air-conditioning system as a medium to cause the spread, spread and cross-infection of SARS-like virus has been recognized by experts. As most parts of our country are about to enter the hot summer, the central air-conditioning system The use...

AI Technical Summary

Problems solved by technology

At present, the inlet and outlet air of most central air-conditioning systems are in the state of natural wind, and the transmission pipelines have not been disinfected regularly. Therefore, the quality of the supplied air is difficult to guarantee

Some experts proposed to use pipeline robots to regularly disinfect the transmission pipelines. However, if the air supply and return air are not disinfected in real time, there is no guarantee that the transmission of viruses through the central air-conditioning system will be cut off.

After literature search, it is found that the Chinese utility model patent: non-powered central air-conditioning air purification device, patent number: ZL99248066.3, this patent discloses a central air-conditioning system composed of air outlet cover, negative ion ozone generator, negative ion and ozone emission terminals, etc. Type air purification device, which only uses electrodes to generate negative ions and ozone to purify the turbid air of the same air conditioning system, and cannot guarantee the killing effect on bacteria and viruses
